Level of Confidence Evaluation and Its Usage for Roll-back Recovery with Checkpointing Optimization

Increasing soft error rates for semiconductor devices manu- factured in later technologies enforces the use of fault tolerant techniques such as Roll-back Recovery with Checkpointing (RRC). However, RRC introduces time overhead that increases the completion (execution) time. For non-real-time systems, research have focused on optimizing RRC and shown that it is possible to find the optimal number

Vikings and the Western Frontier

The article investigates how and why the Vikings became world-famous. The point of departure is the World Exposition in Chicago in 1893, where an icon for the Viking, a replica of the Gokstad ship, arrived the very same day as Frederick Jackson Turner presented his frontier thesis. The origin of the word Viking, the romantic revival of the Viking, the creation of the Viking Age and the criticism o

Out of the National Closet: Show Me Love

This article deals with the question of heteronormativity, or more precisely, how heteronormativity pertains to the reception of the Swedish film by Lukas Moodysson, Show Me Love (Fucking Åmål).

Computer package generating non-invasive atrial electrograms: Detection and subtraction of QRS and T waves

Computerized systems to localize specific patterns appearing in ECG signal, such as the QRS complex and T wave usually utilize predefined templates. Where the signal is not clean, such as during atrial fibrillation (AF), analysis based on self-similarities of the ECG signal appears to be more stable. The authors describe a software package which uses self-similarity techniques to allow the subtrac

Biological Phosphorus and Nitrogen Removal in a Single Sludge System

This thesis presents studies on biological phosphorus and nitrogen removal in a single sludge system. The primary aim was to investigate the process stability of a single sludge activated sludge system designed for the combined operation of enhanced biological phosphorus (EBPR) and nitrogen removal. A pilot plant at the Sjölunda wastewater treatment plant in Malmö, Sweden, has formed the basis for

The Night is the Mother of Day: Methodological Comments on Three Cases of Religious Visions as Suicide Prevention

During my thirty years in the academic field I have always been interested in biographical studies. The focus has been on significant experiences in the individual’s life, so-called turning points, peak experiences or other decisive and unforgettable moments. Was there a crisis of some kind? And, if this is the case,how did the person in question cope with this low point in his or her life? I lear
